Apolipoprotein A-I (Apo-A1) is a structural and functional protein that constitutes approximately 70% of the protein in high density lipoprotein (HDL).

The reference range of Apo-A1 varies by sex, as follows:

  • Men: Greater than 120 mg/dL (1.2 g/L)

  • Women: Greater than 140 mg/dL (1.4 g/L)

Levels decrease with age.
